Can you provide information for an absolute pressure calibration tester which has both a display and a pump?
We would suggest the PGS40 which is a calibration hand pump capable of producing a vacuum to ~100 mbar absolute which is essential for calibrating an absolute pressure range. The pump is also capable of generating a positive pressure of 40 bar above atmospheric pressure. There are also display options such as the LEX1 which is a digital test gauge for measuring absolute pressure, that can be supplied with the pump.
